People walk home in Ashok Nagar, a slum neighborhood that is far from the city center. It can be very difficult and costly for TB patients who live in the far away slums to get to a health clinic to receive their daily medicines. Transportation to a clinic may only cost twenty cents a day, but that can represent nearly 10% of a patient's salary. Some patients will simply stop going to the health clinics in order to save the transportation money, or in order to not miss work.
